Aussichef firstly, do you really need an 80 or 110litre fridge. As others have pointed out they are large physically and take a lot of power in a day - like 84amps +++ and that is at 5°C on a 30°C day. If my mental maths treats me
well, for every 1°C colder you make the fridge, that will be in the order of 9 amps more per day. Yes, a considerable amount of power.
The other issue with the two compartment fridges, their are neither a fridge or a freezer, and the temperature control in both sides is not easy to control. In the fridge part, to get even temperature, you really have to fit an air circulating fan. Those 40mm or 50mm 12vDC fans that switches on and off with the thermostat.
If you go for a 50litre fridge, and have a Sunbeam Food Preserver that will go towards storing meat etc. for an extended time. I have had an imported unit that I have used for many years and found it to be fabulous. While these type of thing have been available in the past in Australia in small automatic units like this model Sunbeam, they have been extortionate prices of around $400.00. We run our fridge at 2°C to 3°C and never had any issues with anything not lasting. The cost of a 50L fridge and a Sunbeam Food Preserver is a long way cheaper than a 80L or 100L fridge.
This is what I posted only yesterday on the MSN Senior Travellers
Forum
Vacuum packaging can extend food life and the
table below is from the excellent Sunbeam Instruction book (PDF File) available on their website for download.
I believe vacuum packaging to be a more cost effective and better option to those two zone chest type fridges - which are neither one or the other, and do not maintain the correct temperature for food storage - usually in both compartments. Once you have had a dehydrator and vacuum packaging unit, you would not be without either. I can highly recommend this method of food storage for campers and caravaner's. We also have a food dehydrator and vacuum pack all the dehydrated food.
TRADITIONAL STORAGE TIMES WITH
Refrigerated foods ( 5± 2ºC) STORAGE TIMES FOOD PRESERVER
Red meat 3-4 days 8-9 days
White meat 2-3 days 6-9 days
Whole fish 1-3 days 4-5 days
Game 2-3 days 5-7 days
Sliced cured meats 4-6 days 20-25 days
Soft cheese 5-7 days 14-20 days
Hard and semi-hard cheese 15-20 days 25-60 days
Vegetables 1-3 days 7-10 days
Fruit 5-7 days 14-20 days
Cooked and Refrigerated foods (5 ± 2ºC)
Purees and vegetable soups 2-3 days 8-10 days
Pasta and risotto 2-3 days 6-8 days
Boiled and roast meats 3-5 days 10-15 days

Yes i read your post on the other
forum & yes i know about these units & use a tefal one for over 10 years + i am a professional chef & know all about preparing & preserving food of all types lol
but i appreciate your reply
& yes if u knew my family i need a big fridge lol
i have always been told
get one size bigger of whatever yr after as u can be sure in 6 months u will have wished you had
thanks warren

I had our meats 'cryovaced' for our recent outback trip, we were still using red meat after 5 weeks, fresh as the day we put it in the fridge.
We were using a 40L Engel running at around 2 degrees.

Warren,
It is easier to outgrow a small fridge than it is to under utilise a large one. Go as big as your budget allows if you are like me and like to take plenty of stuff, and I know you are LOL.
Keep in mind a big fridge draws big power.
Cheers,
Jim.

In response to David's comments on 84 amps/day, this may be so running it as a fridge and freezer in hot weather. I don't doubt this is possible from my experience.
However running a CF 80 as all fridge, in 25 to 28 C ambient, on 3 lights with the power setting at low (draing 3 amps when running) it cycles on for 4 minutes, then off for 6. Thus it is cycling 40% of the time at 3 amps equals 28.8 amps per day. Put it up to 4 lights and it goes 4 on, 4 off, which is 50% which equals 36 amps per 24 hours.
This I know because I've sat and timed it ( bleep I need to get a life).
I have experimented with running it as a fridge and freezer briefly, and whilst I didn't time the cycles, my multi meter told me it had used a huge amount just running overnight.
Running as a fridge and freezer is only an option if you are travelling a fair distance every day and have a very good dual battery setup, preferably with a large cpacity AGM battery, or if you have a very good solar system.
Cheers,
Jim.

Jimbo the 84 amps a day is from the figures I have in print from Waeco in FRIDGE ONLY mode. The
test was done at an ambient temperature of 30°C and a cabinet temperature of 5°C. From reports from users, the figures appear about right - all I can say, never tried one myself, but Waeco supplied figures have always proven to be pretty accurate. We all use them for calculating solar systems, and to date nobody to my knowledge has questioned them.

David,
Interesting, your comments have prompted me to re-read my Waeco manual and it states that it draws 36 watts AVERAGE on the low setting. I had originally misread this to be 36 watts when running. That would equate to about 72 amps/24 hours, which
mine does not draw according to my observations. Although at night it would obviously draw a lot less.
However 36 watts average would suggest possibly 84 watts when running which equates to about 7 amps. Now when I run it at
home from a 4 amp power supply the "Error" light which is supposed to flash if it is not getting enough power never comes on. If I switch it to "turbo" the light starts flashing. Naybe the power supply is conservatively rated?
Now I'm really confused.
I'm going to call Waeco for some technical advice tomorrow.
Cheers,
Jim.

Jimbo,
We were talking about this in a previous thread. It might have been one of your solar threads. Anyway if you look on the bottom of your fridge it will have a sticker or label or something that says the fridge draws a max current of 7.x amps. I assume this is only when you press the boost button as my manual says when boost is pressed it cools quicker than on the high setting. The manual also says it draws about 3.5 amps or so per hour when running on a particular setting and a certain ambient temp. This means 3.5 amps every hour not just 3.5 amps when the fridge is running and nothing when it is not. So for example if you had a 50% on/off cycle then usng these figures that would mean the fridge is drawing about 7 amps 50% of the time and 0 amps the other 50%. These figures are obviously just a theory guess work thing but I hope you get what I mean.
I'm not at
home atm (away for work til Chrissy) so I can't
check my manual but just look in yours and all the info is there (plus the bottom of the fridge).

I think the US Dept Health or whoevermaintains that a certain temperature must be reached to preserve meat. I am not sure whether food drying units reach the required temp.
I read somewhere drying can be effective in preserving meat if first a higher temp is reached to kill bacteria.
Anyone have any clues?
